Question

a wodden toy is in the shape of a right circular cone mounted on a hemisphere ofthe radius of the hemisphere is 4.2 cm and the total height oftof the toy is 10 .2 cm.Then the volume of the wooden toy

Answer 1

d of sphere is 21cm

r of sphere is 10.5cm

r of cone is 3.5cm

h of cone is 3cm

no. of cones = v of sphere / v of cone

no.of cones = 4/3 pi r cube/1/3 pi r square h

=> 4/3 *22/7 *10.5 *10.5 *10.5 = 1/3 *22/7 *3.5 *3.5 *3

=> 4851 cm cube = 38.5 cm cube

no of cones = 4851 cm cube / 38.5 cm cube

no of cones =126 ans..
